We have been developing the combination process of electrochemical and lithography techniques to fabricate ferromagnetic nanodot arrays for bit patterned media(BPM). In this work, we attempted to fabricate L10-FePt thin films with 20 nm thicknesses and FePt nanodot arrays (diameter; 15 nm, pitch; 35 nm) by electrodeposition and characterized their properties. For obtaining higher coercivity and capability of lower annealing temperature, we also utilized multilayer structure by pulse electrodeposition. As a result, L10-FePt with 20 nm thicknesses exhibited higher coercivity of 12.0 kOe. Moreover, applying pulse electrodeposition to form FePt multilayer enabled to lower the annealing temperature, e.g., perpendicular coercivity of 7.1 kOe was obtained by 450°C annealing. The FePt nanodot array could be formed after annealing, by optimizing the deposition and annealing parameters. |
